How do u solve the top one? And what do I write for the bottom one?

Mathematics
1 answer:
3241004551 [841]3 years ago
5 0

Answer:

17. (2)

Step-by-step explanation:

-5x(x+7)(2x-3)=0

divide both sides by -5

x(x+7)(2x-3)=0

*When the product of factors equals 0, at least one factor is 0*

Set the three factors up to zero

x=0

x+7=0

2x-3=0

solve the equation

x=0

x=-7

x=3/2

this equation has three solutions from least to greatest being; -7,0,3/2

And for number 18, that equation cannot factor, that being the error.

Let me know if this was unclear, I'll be happy to further help!

The points (4, 9) and (0, 0) fall on a particular line. What is its equation in slope-intercept form?
BlackZzzverrR [31]

Answer:

The equation of the line would be y = 4/9x

Step-by-step explanation:

In order to find the equation, we first need to find the slope. We can do this by using the slope equation with the points.

m(slope) = (y2 - y1)/(x2 - x1)

m = (9 - 0)/(4 - 0)

m = 9/4

Now that we have this, we can use point-slope form along with one of the points to get the equation.

y - y1 = m(x -x1)

y - 0 = 4/9(x - 0)

y = 4/9x

Austin is building a miniatuer replica of the empire state building.The actual empire state building is 1,423 feet tall and 6,00
dybincka [34]

Answer: 14cm

Step-by-step explanation:

From the question, we are informed that Austin is building a miniatuer replica of the empire state building and that the actual empire state building is 1,423 feet tall and 6,000 feet wide

We are further told that Austin's replica has a width of 60 centimeters. This implies that the scale of 1:100 was used where 1cm represents 100 feet

= 60:6000

= 1:100

Therefore, the height of his empire state building replica rounded to the nearest centimeter will be:

= 1423/100

= 14.23cm

= 14cm approximately

No it’s not a translation
